Study of Behaviour of Paramagnetic Molecules on Surfaces
Bouček, Martin ; Procházka, Pavel (referee) ; Hrubý, Jakub (advisor)
This thesis deals with behaviour of paramagnetic molecules of copper(II) pthalocyanine (CuPc), hemin and bis(dibenzoylmethane)copper(II) ([Cu(dbm)2]) on surfaces of glass and polycrystalline gold. Additionally the [Cu(dbm)2] is studied on graphene surface. Molecules are deposited on substrates via wet chemistry methods. They are studied after deposition with atomic force microscopy (AFM), electron paramagnetic resonance (EPR), scanning electron microskopy (SEM) and X-ray photoemission spectroscopy (XPS).

Study of Wet Deposition of Atmospheric Aerosol using Horizontal Hydrometeors.
Zíková, Naděžda ; Pokorná, Petra ; Pešice, Petr ; Sedlák, Pavel ; Ždímal, Vladimír
Processes between atmospheric aerosol (AA) and clouds, source of large uncertainty in weather and climate changes estimations, were described on fogs at Milešovka, meteorological observatory of the Institute of Atmospheric Physics. For the description of the AA properties, online measurement of outdoor particle number size distribution (PNSD) in the size range 10 nm – 20 μm was conducted using SMPS and APS spectrometers. The sampling system consisted of a heated whole air inlet, and PM2.5 sampling head, being switched by an automatic valve. From the difference between PNSD sampled by whole air inlet and by PM2.5 inlet, PNSD of activated particles (aPNSD) was calculated. The aPNSDs differ with hydrometeor type and depend on air mass history, with a stronger influence on freezing fog AA.

Atmospheric deposition of nitrogen and phosphorus in the Czech republic and round the world.
SUCHÁ, Jitka
This bachelor thesis is focused on the atmospheric deposition of nitrogen and phosphorus in the Czech Republic and round the world. For easier understanding of atmospheric deposition in the thesis there are shortly explained terms such as the source of pollution, emissions and air pollutants, which are interdependent and often interact. There are presented different types of atmospheric deposition, their detailed classification, their collection and the process of determining the size of atmospheric deposition. Furthermore, this thesis gives the current value of atmospheric deposition in European and non European countries and the values in the Czech Republic, where the trend of atmospheric deposition from the fifties to the present is shortly described. The thesis presents the station network in the Czech Republic, its functions and methods of data collection, which are still used to evaluate the air quality situation in Europe in the EMEP programme, where you can find information about other European countries. Then the values of atmospheric deposition of nitrogen and phosphorus in the U.S., especially on the east coast and central parts of the United States of America, and China are presented. The last part of the thesis is focused on atmospheric nitrogen deposition value development in the Czech Republic selected, more or less affected areas in the Czech republic.
